Application filed May 24,1905. saai in. 261,933.

To all whom it may concehn:

Be itknown' that I, HANS L. CHRISTIAN- SEN,a citizenof the United States, residing in Boston, in the county of Suffolk and State of Massachusetts, have invented an Im rovement in Pneumatic Tires, of which t e following description, in connection with the accompanying drawings, is a specifi ation,

like letters on the parts.

This invention relates to a pneumatic tire, and has for its object to rovide a tire of novel construction, as wil be described,

drawmgs represent glike which is especially ada ted for use on the wheels of automobiles, icycles, andlike vehicles, whereby the neumatic tire may be secured to the rim of the wheel without the use of cement.

In accordance with this invention the pneumatic tire is provided with a plurality of transversely-extended passage-Ways, ha'ing their walls attached air-tight to the wa. sot

- the tire, and the walls of said passa e-ways may be formed integral with the wal s of the tire. i

The tire may be secured tothe rim of the wheel by lacings, cords, or straps, or like fastening devices, which are extended throu h the passageways and about the rim of t e wheel. The lacings referred to may be passed through a shoe or protective covering for the tread of the tire, by'which means said shoe is securely fastened in lace.

The tire may be provide on its inner circumference with one or more rojections or lugs, which extend into suita le sockets in the rim of the wheel and prevent cree ing of the tire. The tread of the tire may e pro- 'vided with a protective band or plate of sheet metal which is interposed between the shoe or covering and the tire and serves to protect the latter agcinstipuncture.

These and other teatuieisaof this invention will be pointed out in the c ims at the end of this specification.

Figure 1 is a side'elevation of one form of wheel provided with a pneumatic tire embodying this invention; Fig. 2, a transverse section, on an enlarged scale, of the tire shown in 1; and Fig. 3, a modification to'be re ferred to".

Referring to the drawings, a represents the rim, 7) the hub, and c the spokes, of a wheel provided with a pneumatic tire'dembodying this invention. The tire d, rubbenor other suitable material,in,,acordance with this invention is provided with a .plural1ty of passageways e, extended,- transversely of the tire and having its walls f attached to the walls of the tire, so as to form an air-tight connection therewith. The assage-ways e haveextended through them acings, straps, cords, or like fastening devices '11, by means of which the tire may be detachably secured to the rim a of thewheell The lacings t may also pass through suitable eyes-or holes 3 in a shoe or covering it, of leather or other suitable material, which serves to rotect the tire from wear. The tire d mag e provided on its inner circumference Wit lugs or projections m, which enter sockets n on the mner circumference of the rim a, by means of which cree ing of the tire on the rim is prevented. he shoe 7c may be provided with metal rods Z at its treadportion to increase the. wearin qualities of the shoe, and between the oe and tire an armor 0 is interposed to prevent puncture.- The armor 0 may be made in the form of a metal, late, band, or ribbon, which ma be embed ed in a thickened portion :0 o the tire, which thickened ortion forms thetread of the tire.

Additions. tubes r may be extended subsired.

I'may prefer'toemplo the lacings as a means for attaching the s oe-to the tire; but

I do not desire to limit my invention in this respect, as the shoe may be secured in lace by means of buttons s extended throng the shoe into the tubes (see Fig. 3,) or it'may otherwise be secure to the tire.

From the abov description it will be seen that the tire may e secured to the rim of the wheel in a minimum time and maybe quickly detached therefrom, as it is not required to be cemented to the rim to retain it in place thereon, and convenient means are adorded for attaching the tire and its shoe to the rim of the wheel. The shoe is maybe made of sufficient size to lap under the rim (1,515 so desired.

I claim- 1. The combination with a wheel, of a pneumatic tire therefor provided with transverse nassa 'e-ways, and la 111 s extended I through as o passageways and a out the rim of the tirlieel 'fbr attaching the tire to the Wheel, substantially as described. I
